PROJECTOR-STOPPER.

SPECIFICATION forming part of Letters Patent No. 305,221, dated September 16, 1884:.

Application filed July 26, 1884. (No model.)

To 0.7/7, whom it may concern:

Be it known that we, Gnonons PINAUD and PIERRE GUICHARD, of the city of Paris,France, have inventeda new and Improved System of Stopper for Bottles and Flasks, called Projee torStopper, of which the following is a full, clear, and exact description.

The invention for which we hereby apply for a patent is relative to a system of stopper or cork capable of being adapted to all kinds of bottles and flasks. By this system. is obtained the projection of the liquid contained in the flask provided with our proj ector-stopper. The projection is produced by pressure applied to a hollow india-rubber ball fixed to the top of the stopper, and by the return of the said ball to its original form and volume. The liquid may be projected in one or more jets, according to the number of holes pierced in the ball. The holes are of course capillary, so as to allow of the passage of very thin jets only.

In order that our system'of projectorstopper may be thoroughly understood, we will now proceed to describe it in detail, and will in course of the description refer to the accompanying drawings.

In these drawings, Figure 1 represents a longitudinal section of the axis of the stopper.

Fig. 2 shows in elevation the application of our system to a flask. Fig. 3 is a longitudinal section of one of our stoppers. Unlike Figs. 1 and 2, this stopper is not provided with a tube plunged in the liquid. Figs. 4 and 5 6 and 7 show (on an enlarged scale) in plan and longitudinal section the details of the stopper without the tube which plunges in the liquid, and also without the ball which produces the aspiration and the projection of the liquid.

As may be seen by reference to Figs. 1, 3, 4, 5, 6, and 7, our apparatus is composed of a cork, a, pierced through its center longitudinally, so as to form a cylindrical or conical hole. In this hole is inserted a tube, 2), surmounted by a flange which rests against the top of the cork, and which forms part of. or is soldered to a larger tube, (1, communicating with the tube 12, of which it is the prolongation. The tube dis widened at its upper end, so as to form a spherical cap, 0. Another tube, f, is screwed into the tube (1.

The tube f is terminated by a widened part, g, similar in form to the spherical cap e, into which it fits. The hollow ball t is held between the two parts 6 and g. The said ball is provided at its lower part with a circular opening, into which the tube f is introduced in such a manner that the edges of the opening in the hollow ball come into contact with the external surface of the cap g. It follows that when the tube f is screwed home in the tube d the ball is pressed and held tightly between the spherical parts 0 and g. The spherical cap g is provided with a small metallic arm, j, at either side of which are openings It, which communicate directly at their lower extremities with the tube f. These openings are covered on the top by a small india-rubber washenl, attached by its center to the arm j, and capable of being raised at its circumference, so as to give admission to the liquid into the hollow ball '5.

In Figs. 1 and 2 it is seen that a tube, m, is fitted into the tube 6, and forms the prolongation of the latter, and plunges into the flask to which is adapted our projector-stopper. Now, the hollow ball 1' being provided with a small hole, a, it su'flices to press the ball slightly and then allow it to reassume its original volume or capacity. This pressure and subsequent expansion sucks the liquid and causes it to enter the ball, passing on its way through the tubes m, b, and f, and raising the edges of the circular valve Z. The liquid having thus'eutered the hollow ball, if the latter be again eompressed,the valve Z is pressed against its seat, and the liquid is projected in a thin jet through the capillary-hole a.

Fig. 3 represents a stopper of the same system asthe one just described; but it is not provided with a plunging tube. In order to use this projector-stopper, it suffices to turn the flask upside down and to press'the hollow ball and allow it to expand alternately.

\Ve may naturally give any form or dimensions to the ball, and the metallic partsof our apparatus may be composed of wood, ivory, india-rubber, c. Likewise the plunger-tube may be made of glass, of metal, wood, ivory, or any other material, or it' may be altogether dispensed with, as has been above explained.

We claim Theproj ector-stopper, either provided or not two spherical pieces a and g, as above de-' scribed, and for the purpose set forth.

provided with hole or, and held between the The foregoing specification of our new and improved system of stopper for bottles and flasks, eallen' projector-stopper, signed by 15 us this 5th day of July, 1884.
